INLET-VALVE.

Specification of Letters Patent.

Application filed January 12, 1915, Serial No. 1,862. Renewed May 12,1916. Serial N 0. 97,185.

To all whom it may concern:

Be it known that I, Grusnrrn GANNESTI, a subject of the King of Italy,residing at New York, in the county of Bronx and State of New York, haveinvented new and useful Improvements in Inlet-Valves, of which thefollowing is a specification.

This invention relates to inlet valves for flush tanks and it consistsin the novel features hereinafter described and claimed.

An object of the invention is to provide a valve of the characterindicated which is of simple and durable structure, positive in itsaction and which may be easily and quickly operated automatically topermit water to flow into a tank or other receptacle.

With the above object in view the valve includes a casing having at oneside an inlet nipple and at its opposite side a guide. The said valve isprovided between the inlet and the guide with an outlet. Means isprovided for supporting the valve casing at the side of a tank or otherreceptacle. A valve proper is movably mounted in the casing and isadapted to seat against one end of the nipple and the stem of the valveproper is slidably received in the guide. A shaft is journaled in thecasing and is provided with an arm which passes through the stem of thevalve proper and a float mechanism is operatively connected with thesaid shaft.

In the accompanying drawing :Figure 1 is a side elevation of the valve.Fig. 2 is a top plan view of the same. Fig. 3 is a transverse sectionalview of the same showing minor parts in elevation. Fig. 4 is a similarview taken at a right angle to the view shown in Fig. 3.

The valve includes a casing 1 which is provided at one side with alaterally disposed guide 2. The said casing is provided at its oppositeside with an opening in which is screw threaded a nipple 3. The nipple 3is provided with an interiorly located valve seat 4 the sides of whichare spaced from the inner walls of the said nipple as best shown in Fig.3 of the drawing. The casing 1 is provided at a point between the nipple3 and the guide 2 with a water outlet 5 and the said outlet 5 isprovided with a bracket 6 by means of which the casing 1 may besupported upon a wall 7 of a tank or other receptacle. A valve proper 8is movably mounted in the casing 1 and is adapted to close against theseat 4 of the nipple 3 as shown in Fig. 3 of the drawing.

The valve proper 8 is provided with a stem 9 which is slidably receivedin the guide 2 and the said stem 9 is slotted as at 10 at a pointbetween the guide 2 and the valve proper 8. A shaft llis journaled inthe lower portion of, the casing 1 and an arm 12 is fixed to the saidshaft and the upper portion of the said arm is received in the slot 10of the valve stem 9. An arm 13 is fixed to the outer portion of theshaft 11 and is provided at its free end with a sleeve 14 having a setscrew 15. A rod 16 is adjustably mounted in the sleeve 14 and is adaptedto be secured at an adjusted position therein by means of the set screw15. A float 17 of any desired pattern is fixed to the lower I end of therod 16. The nipple 3 is adapted to be connected in any suitable mannerwith a water supply pipe 18.

The operation of the valve is as follows: Presuming that the tank orreceptacle in which the valve is located is supplied to a predeterminedlevel with water the float 17 and arm 13 are held in elevated positionswhereby the valve proper 8 is held in a closed position against the seat4 and the passage way through the nipple 3 is closed. As soon as thewater is withdrawn from the tank or receptacle the float l7 falls bygravity and the arm 13 is swung whereby the shaft 11 is turnednand thearm 12 is swung about the axis of the shaft. This movement on the partof the arm 12 moves the valve proper 8 away from the seat 4C andconsequently the passageway from the water through the nipple 3 isopened and the water may flow from the pipe 18 through the said nippleinto the casing 1 and then out through the outlet pipe into the tank orreceptacle. When the water in the tank or receptacle assumes its normallevel the float 17 and free end of the arm 13 are elevated and the shaft11 is turned whereby the arm 12 is swung and the valve proper 8 iscarried back to its seated position against the seat A of the nipple 3and consequently the passageway of the water through the said to closeagainst the seat and having a stem tachably mounted at the lower end ofthe 10 Which is slidably received in the guide, said casing.
